Error while importing .json format

Hi all,
I am facing an issue while importing a .json file using the RESTFul web service data store. SAP Data Services 4.2 SP8 throws below error:

“An error occurred while importing metadata. No other information is available.”

Does SAP Data Services accept the input as .json or.xsd for making the request to json based web service using the Restful Web Services adapter?

Any help is much appreciated!!!
